System.IO.FileLoadException: Could not resolve assemble "System.Text.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51" when using WTelegramClient with DllExport

[2x0c0v8b]

Steps to reproduce:

Create new class library project using .NET Framework 4.7.2
Run DllExport

Then install WTelegramClient NuGet package.
Adding a simple method creating WTelegram.Client. It failed when running from either unmanaged either managed.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

namespace telebird_dll
{

    static public class A
    {
        static WTelegram.Client client;

        [DllExport(CallingConvention = System.Runtime.InteropServices.CallingConvention.Cdecl)]
        public static void init(IntPtr x)
        {
            //string cur = Marshal.PtrToStringUni(x);
            //if (cur != "")
            //    cur += "session.dat";
            client = new WTelegram.Client(17349, "344583e45741c457fe1862106095a5eb");
        }

        // ...
    }
}

When running from managed program (C++ CLR) got this error:

Необработанное исключение: System.IO.FileLoadException: Не удалось загрузить файл или сборку "System.Text.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51" либо одну из их зависимостей.

   в mainCRTStartupStrArray(String[] arguments) в D:\a\_work\1\s\src\vctools\crt\crtw32\msilcrt\mcrtexe.cpp:строка 247

If just export this function without DllExport and run in managed code it run successful.

Hello,

Please read https://github.com/3F/DllExport/wiki/PreProc#alternative-to-assemblyresolve

Your demo project is a bit complicated so I've checked the mentioned WTelegramClient from scratch using the way for AssemblyResolve. Try for example,

static A()
{
    static Assembly _Load(string path)
    {
        if(!File.Exists(path)) return null;

        Console.WriteLine("Load: " + path);
        return Assembly.LoadFrom(path);
    }

    AppDomain.CurrentDomain.AssemblyResolve += (sender, args) =>
        _Load(Path.Combine
        (
            Path.GetDirectoryName(typeof(A).Assembly.Location),
            args.Name?[..args.Name.IndexOf(',')] + ".dll"
        ));
}

[DllExport]
public static void init(IntPtr x)
{
    ...
    WTelegram.Client client = new(17349, "344583e45741c457fe1862106095a5eb");

Note .NET DllExport is not required when you're using C++/CLI because .NET classes are accessible as well as native C++ types.

When running from managed program (C++ CLR) got this error:

[2x0c0v8b]

Thank you! Your solution with AssemblyResolve worked.

P.S. I tried to run DLL from managed program because running from unmanaged just crashes the program and vs debugger shows "Access violation" error

Make sure Debugger Type is Mixed (.NET Framework)

Also note Step Into in 1.8.0 will not* work properly if you configure processing through my (3F's) assembler.
*Actually I have already added support at least for the portable pdb 3F/coreclr#3 (comment) but it hasn't been released yet
